Problems accessing results in websites

Hello,

today I was trying to book a flight and encountered problems on several websites: Air France, Iberia and easy jet.

i could not see the results of my searches. It would either keep on loading without showing me the results or it would show an error message.

i did all the updates and restarted my Mac but nothing changed.

i also downloaded google chrome but it was the same problem.

ib the end I booked my flights on my iPhone which is of course less convenient.

any idea why that is and how it can be solved for next time?

many thanks!
